STEAM-HEATING AIEARATUS.

Specification of Letters Patent.

Pei/tented Apia 25, 191i Application filed August 4, 1910. Serial No.575,473.

To all whom it may concern:

Be it known that we, lVILLIAM T. Peon United States, residing atLynchburg, in

the county of Campbell, State of Virginia,

have invented certain new and useful linproveinents in Steam-HeatingAppnratus; and we do hereby declare the following to bee full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to steam. heating apparatus. l

The object of the invention is to provide a steam heating apparatusadapted tocontrol automatically the draft of the boiler and therebysecure a uniform steam pres sure and to enhance the efli'ciency of thes; stem with which it is associated.

ll ith the above and other objects in View the invention consists in thedetails of construction and in the arrangement and coinl'iination ofparts as will be hereinafter more fully described and particularlypointed out in the appended claim.

In describing the invention in detail referencr will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several-views; and in which v Figure 1 is aside elevation of a boiler with the invention associated therewith;

Fig 51, an enlarged side elei 'ntion of the invent i; 3, a section onthe line 3-3 of -n, and, Fig. 4, a section on he line ll g. 3, thereservoir being partly broken away.

l lorl'erring to the drawings, represents the boiler which may be of anydesired form and which is provided with a check damper l1 and :1 draftdoor 12 located respectively at th smoke pipe or flue and at the bottomthe boiler for controlling the draft through. the smoke pipe'orconnection and through. the base of the boiler to the fire, and thesedampers are controlled by means hereinafter described for maintaining auni forn'i steam pressure throughout the system with which the boiler i0is associzited.

"the pressure regulator is indicated generally by A and comprises asubstantially elliptical casing provided with an upper opening 13 and a,lower opening 14. A pipe connection 15 has one end mounted in theopening 13 and its other end communicating with the atmosphere throughthe chimney Another pipe 17 has one end secured in the opening 14 andits other end communicating with the interior of the boiler 10 below thewater line. From this construction it will be apparent. that as thepressure in the boiler 10 increases the water contained there in will beforced through the pipe 1Z'.into the casing or reservoir of the pressureregulater. ilournaled in the casing of the. reservoir is a'sliaft 18,one end of which. extends cxteriorly of the reservoir asat 19. l iXcd onthe shaft 18 within the reservoir is an arm 20 which carries at its freeend a fleet 21. Another arm 22 is also fixedly secured in termediate itsends to the exterior ortion of the shaft 18 and has one end terminatingin a pointer 23. Also formed in the arm 22 on opposite sides of itsconnection with the shaft 18 are eyes 24 and 25 and a chain 26 has oneend. connected in the eye 24 and its other end secured .to the checkdamper 11, while another chain 27 has one end secured in the eye 25 andits other end to the draft door 12; said chains traveling over-suitablepulleys 28 arranged above the boiler. litemovably mounted upon the outerface of the reservoir adjacentthe pointer is a dial plate 29 which hasindicated thereon a scale of pressures, increasing from its bottomtoward its top. 7

As water is forced by the pressure in the boiler into the reservoir itwill be enparent that the float 21 will be elevated and the shaft 18 inconsequence rotated. This foth tion of the shaft 18 will in turn cause umovement of the arm 22 and effect through the chain connections 26 and27 the opening of the check draft 11 and the closingof the draft door 12and thus decrease the pressure in the boiler- A reverse movement of thearm 22, due to the descent of the float. 21 will in. turn open the draftdoor 12 and close the cheek damper 11', thus raising the pressure withinthe. boiler. llnring; this movement of the nrinQZ the pointer 23 will atall times indicate in connection with the dial plate 29 the pressureexisting within the boiler. In order to prevent the water forced intothe reservoir from passing through the opening there is detachahlymounted in said opening tuhular bushing 30 while a second tubularbushing 31. is detaohably mounted within the bushing 30 end has theouter end of its bore threaded for connection with the pipe 15.Suspended from the lower end of the bushing 31iis a plurality ofU-shaped wires 82 with their bent portions intersecting each other anddisposed across the bore of the bushing 81. Seated upon the bent portionof the wires 32 is a hollow float valve 33, the lower end of which isopen, while the upper end thereof is closed and. ot' conical formation.From this construction it will be apparent that when the water forcedinto the reservoir reaches the level of the float valve 83, the latterwill be raised from its seat upon the bent portion of the wires 32 andelevated so as to close the opening through the bushing 31 and therebyprevent the passage of water through the pipe 15.

As the dial 29 is removable it will be apparent that the figures thereoncan be changed and the reservoir placed at a higher or lower point andthe pointer and dital will still indicate the higher or lower pressures.

What is claimed is:

In a steam heating apparatus, the combination of :1 boiler, a reservoirlocated above the water line of the boiler, having an upperopeningventing to the atmosphere, and a lower opening in communicationwith the boiler below the water line, a bushing mounted in said upperopening, a plurality of U-shaped wires suspended from the lower end ofsaid bushing and extending into the reservoir and having theirbentportions intersecting each other, a fioat valve seated upon the bentportion of said U-shaped wires and guided by the arms thereof during itsmovement to open and close the opening through the bushing, a floatlocated within the reservoir, and a damper and a,

draft door said float.

' In testimony whereof, we afiix' our signatures in presence of twowitnesses.
